Eyemodel - schematic Eyeball

For our Institute of Experimental Ophthalmology (XO), I created a logo representing our main field of application. Additionally, you can find an unmodified eyeball. In terms of printing specifications, the nozzle size is 0.4mm, and retraction is enabled. The model matrix is set to 0.5, while layer height is 0.2mm and wall thickness is 0.8mm. Fill density is at 100%, print speed is 40 mm/s, and print temperature is 220°C. Support structures are not required, and a raft isn't used either. Filament diameter is 2.8mm with a filament density of 1.00. The skirt line count is one with a gap of 3.0, retraction minimum travel is 5.0, retraction speed is 40.0, and retraction amount is 4.5. Travel speed is set at 150 mm/s, while the maximum z-axis speed is 3.0 mm/s. Bottom layer speed is 20 mm/s with a cool down time of 5 seconds. The fan is enabled, and bottom layer thickness is 0.3mm. Object sinking is set at 0.0, and skin printing is disabled. Infill type is lines, solid top layers are included, and fill overlap is 60%. Bridge speed is set at 100 mm/s, with a sequence of loops, perimeters, and infill. The first layer sequence is forced to the specified order, and jumping retraction is enabled. Hopping on movement is disabled. The start G-code includes details about the slicing process, such as the file name, date, time, basic settings like layer height, wall thickness, and fill density. Additionally, it displays print time, filament used, filament cost, platform speed, extruded length, and fan status. The G21 command sets metric values, G90 ensures absolute positioning, and M107 starts with the fan off. The printer moves the X/Y axis to its minimum endstop (G28 X0 Y0), followed by moving the Z-axis to its minimum endstop (G28 Z0). Then, it lowers the platform 15mm at a speed of max_z_speed (G1 Z15.0 F{max_z_speed}). The extruded length is zeroed (G92 E0), and 3mm of feedstock is extruded (G1 F200 E3). Afterward, the extruded length is zeroed again, followed by setting the speed to travel_speed (G1 F{travel_speed}), and displaying 'Printing...' with M117.
